This is a large pack with something on the order of 150 mods, many of them large and involved. Clients will likely need at least midlevel hardware to get acceptable performance, and the hosting server, if applicable, will need to be able to support a large world with a great deal of activity. If running singleplayer, you will want to meet both client and server requirements (except bandwidth).
